Least Common Multiple of 420, 121, 12

Least common multiple or lowest common denominator (lcd) can be calculated in three ways

• Least Common Multiple of 420, 121, 12 by common division method
• Least Common Multiple of 420, 121, 12 with GCF Formula

∴ So the LCM of the given numbers is 2 x 2 x 3 x 35 x 121 x 1 = 50820

The formula of LCM is LCM(a₁,a₂,a₃....,a_n) = ( a₁ × a₂ × a₃ × .... × a_n) / GCF(a₁,a₂,a₃....,a_n) x common factors(if more than 2 numbers have common factors).

We need to calculate greatest common factor of 420,121,12 and common factors if more than two numbers have common factor, than apply into the LCM equation.

GCF(420,121,12) = 1

common factors(in case of two or more numbers have common factors) = 12

GCF(420,121,12) x common factors =1 x 12 = 12

LCM(420,121,12) = ( 420 × 121 × 12 ) / 12

LCM(420,121,12) = 609840 / 12

LCM(420,121,12) = 50820

∴ Least Common Multiple of 420,121,12 is 50820

Here are some samples of LCM of two or more Numbers calculations.

• LCM of 780, 693, 70
• LCM of 317, 196, 61
• LCM of 850, 612, 32
• LCM of 313, 123, 24
• LCM of 376, 112, 39
